Ebyte MA02-XACX0440 RS232 Industrial Level Serial port I/O networking module
[Specifications]：4AI+4DO
[Interface]：RS232
[Installation method]：positioning hole
[Size]：115*90*40mm
[Introduction]：MA02-XACX0440 supports the acquisition of 4-channel sensor analog input (AI), which is converted to serial port (RS232) and data is transmitted to configuration software or PLC. The serial port I/Onetworking module (also called "remote IO") that realizes the remote acquisition and control function by issuing commands through the serial port to control 4 relay switch outputs (DO).
